<TL; DR> I’ve built a TCPSyphon Server myself in Java and tried to circumvent some of the flaws of the original Version </TL; DR>

Maybe you heard about Syphon. “Syphon is an open source Mac OS X technology that allows applications to share frames – full frame rate video or stills – with one another in realtime” (Link). It was originally intended to only work locally and not be shared between different Hosts on a Network. Fortunately someone took care of this and built a set of applications to share “Syphon data” between multiple Computers. Actually it doesn’t: It renders local Syphon data into single images (jpeg, for example), applies a compression and sends them over the network. Anyways, this is one of the applications you don’t get around as a VJ. You just HAVE to have it: TCPSyphon.

The person behind the TCPSyphon-apps also built a client for the Raspberry Pi. The TCPSClient. Now things become really interesting.

This idea caught me a while back and it took quite some effort to rebuild it from the leftovers a few days ago. Kids don’t forget: The only difference between noodling around and being a true specialiologist (they don’t call me “Doktor Andy” for nothing) lies in a reusable form of documentation. Fortunately I got this website. What would I do without it.

<TL; DR> video from Mac to Raspberry via network</TL; DR>

The approach uses Syphon, Open Broadcaster Software (obs), nginx and Omxplayer. I guess this ain’t too revolutionary. Using RTMP is quite a common task to distribute video. But it’s a good idea to have it all written down at least once. Furthermore I couldn’t find any kind of writeup like this covering this topic so … it’s okay.
